Description
Technical field:
The invention belongs to the organic solid castoff processing technology field, be specifically related to method and device thereof that the oxygen-consumption-humidity-temperature of a kind of kitchen excess aerobic compost jointly controls.
Background technology:
Along with human life quality's raising, the quantity of kitchen excess also in surge, owing to its moisture and the very high municipal wastes that is different from of organic content, can be rotted in the short period of time, degrade.Burn if the kitchen excess mixes with other municipal wastess, whole thermal value does not reach sends out the heat that point requires; If mix with other municipal wastes and to carry out landfill, its water ratio is high, can produce a large amount of percolates, and burning and landfill can be wasted great number of organic matters and nutrient in the excess of kitchen again.Therefore, be necessary rubbish from cooking is carried out individual curing.
Composting technology is domestic and international application one of organic solid castoff treatment process the most widely, and this technology is simple and easy to do, can kill wherein most of pathogeny mikrobe.Aerobic compost is because have advantages such as the resource utilization degree is high, the processing back is little to environmental hazard, the low technology of processing cost is simple; Become biological treatment relatively more commonly used; It mainly is to supply with a certain amount of gas to the heap body to make the heap body keep certain oxygen concentration; Be organic waste supporting composting conditions bottom fermentation, intensification well, reach purposes such as sterilization, deodorizing, stabilization.
Because aerobic compost is the biochemical reaction process of a complicacy; Its fermenting process receives influence of various factors; Like water ratio, temperature, air flow etc., each influence factor all possibly become the key constraints of microbial survival, growth, reaction in the total process of aerobic compostization.The too high meeting of humidity causes the compactness of windrow to increase, and porosity reduces, and oxygen supply is not enough, and organic matter degradation rate reduces, the compost cycle stretch-out; Humidity cross low can restriction micro-organisms metabolism, cause microorganism active to descend, the compost material difficulty of becoming thoroughly decomposed.Through measuring, optimum humidity is 50%-60%, is higher or lower than this humidity range and all will has a strong impact on the success of compositing system and the quality of product.Temperature is a microbial life active important symbol in the windrow, directly influences speed of reaction, is the determinative that can compost carry out smoothly.On the one hand, temperature is directly determining the kind and the fermented type of superior microorganism, in the different stages, different optimal temperatures is arranged; Meanwhile, microbial reaction also influences the temperature of reaction system.Therefore, be vital in each period conditioned reaction actuator temperature to corresponding optimal temperature to the success of compost.
But because the limitation of control method causes traditional composting process to have following several shortcoming all through the ages: one of which, compost length consuming time; Its two, composting efficiency is low.Compost reactor in the past all is through regulating air flow for the adjusting of humidity and temperature.Ventilation can provide competent oxygen, removes excess carbon dioxide.But air flow is crossed conference and is caused the loss of heat, water vapor, makes NH
3Burst size increases, and influences compost speed, reduces the compost product quality.Problem is, general being difficult to through only regulating the requirement that air flow satisfies oxygen-consumption, humidity, temperature simultaneously.Regulation mechanism in the past is single factor Feedback mechanism, is that feedback condition is controlled the startup of blower fan and closed with humidity or temperature.Often another factor then is in the level that suppresses the compost reaction.In addition,, also possibly cause oxygen-consumption to be crossed and lowly not satisfy the minimum oxygen requirement of mikrobe, influence microbial reaction if the air flow that feedback obtains is low excessively.Above factor directly has influence on the success or failure of compost and the quality of product.Therefore; Present stage mainly concentrates on the compost process of how accelerating to the research that improves composting process, raising compost final product quality; Thereby improve the surplus compost effect in kitchen, guarantee fertilizer efficiency, also reduce simultaneously because the bad smell that the release of ammonia causes and to the pollution of environment.
Summary of the invention
To the single deficiency of existing process adjustments mechanism, the invention provides the device that the oxygen-consumption-humidity-temperature of a kind of kitchen excess aerobic compost jointly controls, and to the multivariable control method of oxygen-consumption, humidity, temperature combined regulating.
